This is a little tricky because I don't think either guy is very good. Kaan Ofli has overrated BJJ but can be sneaky with his scrambles and power. Javier Reyes is a gamer, but sloppy and not great at any one thing. I am going to pick Javier though because he is unquestionably the more dangerous of the two and even though he has 19 finishes, he might have the better cardio as well.

Kaan Ofli

Kaan Ofli is a BJJ blackbelt with ok takedowns, ok scrambles and ok striking and random power. He is busy on the ground and always looking for something. He is not the longest guy in the world so does rely on strength to control positions and work in sweeps. He's a short compact guy who can be hard to move around. He can be hittable and his chin is somewhat questionable. He is coming off the decision win over Yizha.

Javier Reyes

Javier Reyes is a busy striker who throws a long jab and lots of kicks. He isn't insanely technical, but he is always doing something. He has grappling as well with upper body takedowns and decent BJJ. His traditional takedowns aren't great but he's tough and scrambles well. He has 28 fights and is 32 years old, but still needs to clean some things up. He is coming off the finish win over Douglas Silva de Andrade in his UFC debut.
